可以使用关联规则挖掘中的支持度(support)、置信度(confidence)、提升度(lift)三个指标来对数据进行筛选和排序。其中,支持度表示一个规则在总体数据集中出现的频率,置信度表示在前提条件下,结论成立的频率,而提升度则表示结论与前提条件之间的关联性,即支持度与置信度的比值。
根据某个指标排序,可以将数据按照该指标大小进行排序。例如,按照支持度从大到小排序,可以先计算每个规则的支持度,然后按照支持度大小进行排序。同样的,也可以按照置信度或提升度的大小进行排序。

sing a song?
Sure, here's a song:
Verse 1:
I woke up this morning feeling blue
Thinking 'bout all the things I gotta do
But then I heard a bird outside my door
Singing a melody I couldn't ignore
Chorus:
Sing, sing, sing your heart out loud
Let your voice be heard, don't hide in the crowd
Sing, sing, sing with all your might
And you'll feel the joy in every note you ignite
Verse 2:
I started humming along with the bird
Feeling lighter with every word
The weight of the day began to lift
As I sang out my worries and my gift
Chorus:
Sing, sing, sing your heart out loud
Let your voice be heard, don't hide in the crowd
Sing, sing, sing with all your might
And you'll feel the joy in every note you ignite
Bridge:
It doesn't matter if you're out of tune
Or if you're feeling like a buffoon
Just let your voice be free and true
And the music will carry you through
Chorus:
Sing, sing, sing your heart out loud
Let your voice be heard, don't hide in the crowd
Sing, sing, sing with all your might
And you'll feel the joy in every note you ignite
Outro:
So go ahead and sing your song
Let your spirit soar, don't hold back for long
Sing, sing, sing and never stop
For the music is the beat of life's beautiful backdrop.
tkiner canvas怎么使 图形处于最上层?
可以使用`tkinter.Canvas.lift()`方法将图形置于最上层。比如要将名为`my_rectangle`的矩形置于最上层,可以使用以下代码:
```python
canvas.tag_raise("my_rectangle")
```
其中,`canvas`是你的`tkinter.Canvas`对象,`"my_rectangle"`是你的矩形的标签名。这将使矩形置于所有其他图形的上方。
